Role and Designation during the time: Team Leader
CE 2.2 Project Background
CE 2.2.1 Characteristics of the project
This project is to produce the reinforced concrete design for a pedestrian bridge spanning
a dual carriageway road. This project shall be designed to Eurocode 2. Construction is proposed
to be carried out in two phases. One half of the pedestrian bridge is constructed first by diverting
traffic to the other carriageway and the other half is construction once the first half is completed
and the carriageway over it is opened to traffic and at the same time allowing traffic from the
carriageway to be diverted and carry out construction of the remaining pedestrian bridge.
CE 2.2.2 Objectives developed for the project
 To make pedestrian of six spans with three continuous spans on each side
 To carry out moment distribution analysis for resting the R.C. beams

 To calculate the dimension of the project components and constraints
 To complete the project successfully within the expected timeline
 To keep the budget of the project balanced
 To play the proper role of the leader
CE 2.2.3 My area of work
I had to develop the design that was capable of immune to the factors those could
possibly influence the entire project delivery. Slab designing was the sector on which I to work
solely and develop a sophisticated model that can be helpful in leading a successful project. I
used the following factors for the slab design.
Specification:
 Qk = 5kN/m2
 Design life = 50 years
 Fire resistance = R60
 Exposure class = XC3
Materials:
 Fck = 30 N/mm2
 fyk = 500 N/mm2
 Unit weight of reinforced concrete = 25 kN/m3
 Assume Øbar = 10mm
 Slab thickness:
 -minimum thickness for fire resistance = 80mm
 -Estimated thickness, considering deflection control =
2500/26 = 96mm
 We assume h = 150mm
